SPECIFICATION forming part of Letters Patent N o. 600,943, clated March 22, 1898. Application filed January 20, 1897. Serial No. 619,&369. (No model.)

TO all whom it ntcty concern:

Be it known that I, NICOLAS BOSMANN, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Methods of Refrigeration; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

This invention relates to certain new and useful improvements in refrigerators or cooling-boxes, and more especially to that class where a large space is to be kept cool and at a uniform temperature.

The object of the invention is to provide an ice-receptacle just above the storage-space of the refrigerator having tubes with flaring or funnel-shaped months opening into said storage-space for the descent of the cold air from the ice-receptacle, and other tubes of similar form for the air, after becoming somewhat heated or warm, to pass up into the cooler.

A further object of the invention is to arrange the pipes so that a number of them will enter the top of the tubes which communicate with the storage-space and create a draft by suction by reason of the Volume of air from the pump or fan.

This invention is very simple, cheap, and durable in construction; and it consists in certain novel features of construction of parts and combinations more fully described hereinafter and particularly pointed out in the claims.

In the drawings, Figure l is a cross-section of a refrigerator, showing the cooler or iceu receptacle in the upper portion thereof. Fig. 2 is a central longitudinal section through the cooler or ice-receptacle. Fig. 3 is a top plan View of the cooler, the caps and slats being removed. Fig. 4: is a horizontal section showing the ice or water receptacle and the series of pipes and tubes in plan, the arrangement of the pipes being somewhat different from that shown in Fig. 2. Fig.- 5 is a longitudinal section on the line 2 2 of Fig. 4, the arrangement of the pipes being the same as in Fig. 4:. Fig. 6 is a horizontal section, the inner wall being removed and the pipesarranged similarly to those shown in Fig. 3; and Fig. 7 is a detail View showing the drain for sweet or the like from the air-pipes.

In the drawings, a is the refrigerator,` and b the ice or water receptacle.

c indicates a fan having a Conduit and flaring mouth d.

f are the tubes forming air-passages between the ice-receptacle or cooler and the storage-space below;

The ice-receptacle b is located near the top of the refrigerator' and rests on suitable brackets g, leaving a space all around the receptacle for the circulation of air through the whole refrigerator.

e are pipes, any number of which may be employed; but I prefer to use six or eight, half of which number pour their Volume of air through the tubes f into the storage-space h, and the other half of the pipes empty into the cooler or receptacle. In the top of the tubes f a coupling t' can be employed, if desired, to connect with pipes e.

j is an outlet for water when the receptacle is to be entirely emptied, and 70 is a siphon to regulate the quantity of water therein.

The tubes f are provided at their bottoms with flaring or funnel-shaped openings Z, passing through the drain-troughs or waste-conductors m, which are only of slightly greater area than the ice-receptacle and do not entirely divide the refrigerator. At the top of these tubes f are caps n, so arranged on slats n' that they do not close the opening in the tube, but leave space enough for the insertion of a pipe e from the fan and also to allow a draft of air to enter with the pipe and to admit of the exit of the air ascending from the storage-space.

The pipes e are provided with a suitable drain-pipe e', connecting to each series of pipes, as shown in Fig. 7.

In the operation of the device slats are laid across the bottom of the ice-receptacle and the coil of pipes e laid thereon, the mouth of said pipes enterng the flaring mouth di from the fan and the ends thereof entering the tubes f or emptying into the receptacle, thus distributing air throughout the whole refrigerat-or and admitting of a free circulation. u

If it is desired to use the inner wall o with IOO water in the cooler or receptacle, the pipes e are all directed to blow downwardly half through the tnbesf to the storage-space and half into or against the water, which is thoronghly cooled by the passage of the air through the pipes.

The perforations p in the inner Wall o allow the water to freely circnlate between said inner wall and the wall proper of the receptacle, and the pipes ponring their Volume of air between said inner and onter walls has the same effect as it does within the inner wall. Afree, uniforn, and continnons circnlation of air is also produced.

It is evident that various slight changes might be made in the forms Construction, 'and arrangenents of the parts described without departing from the spirit and scope of my in- Vention. Hence I do not Wish to limit myself to the exact Construction herein set forth, but consider myself entitled to all such changes that fall within the spirit of the invention.

Having thus fully described my invention, what I claim isl. In a refrigerator, the combination of a cooler or ice-receptacle in the upper portion thereof, a fan connected With said receptacle by means of a fiaring month, a series of pipes within said receptacle entering said flaring month, a storage-ehamber below said cooler, tnbes forming channels for the passage of air from said receptacle to said chamber, caps over the tops of said tubes and fiarng months por openings at their bottom, the discharge ends of several of said pipes entering said tnbes forming a suction, the discharge ends of the remaining pipes emptying into the cooler and an outlet for waste or sweat, substantially as described.

2. A refrigerator having a cooler or ice-receptacle, a series of air-pipes therein, a fan or the like to force air through said pipes, a drain for moistnre, sweat or the like in said pipes, and circulating-tubes half of which are adapted to receive the Volume of air from the fan and the remainder to allow the ascending air a free passage from the storage-ehamber to the cooler, substantially as described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
